The coin being described is a 2019 Kennedy Half Dollar, produced in the United States. This specific coin is distinguished by its proof finish, which indicates that it was struck with a high degree of detail and clarity, typically intended for collectors rather than for general circulation. Notably, the coin has no mint mark, meaning it was likely produced at the main mint without specific indication of its production location. There is an intriguing absence of detailed specifications such as width, height, diameter, and weight, which typically inform collectors about the physical characteristics of the coin. As a half dollar, its denomination is 50 cents, and it carries a face value of 0.50 USD. However, the mintage is recorded as 0, which implies that there may not be any known examples of this particular coin, raising questions about its actual existence or availability. This coin represents an attractive addition to any numismatic collection, particularly for those focused on Kennedy Half Dollars, and its unique characteristics may contribute to its potential value. It exemplifies the historical and cultural significance of the Kennedy series, commemorating the legacy of President John F. Kennedy since its introduction in 1964.
